Marie: You're not kidding! So how much shoul we tip?
Anneliese: I think the rule of thumb is 10%, but that's what my dad tips and he's cheap so maybe 15%?
Marie: Cool. Hey, "rule of thumb-" doesn't that come from...
Anneliese: ... An old law that said it was okay to beat your wife as long as the stick you used was no wider than your thumb?
Anneliese No, it's an urban legend actually. I read about it once - there was never any such law, not here or in England.
Marie: Really? So someone just made that awful story up?
Marie: Hmm... ... So isn't that pretty much just as disturbing as if there were a law like that?
Anneliese: On the whole, yeah it - AAAH!!
Frenchman: JE SUIS DE RETOUR!
